Nineteen patients aged between 4 days and 40 years with Ebstein's anomaly of the tricuspid valve have been examined with echocardiography. The diagnosis was verified with angiocardiography in all but one patient. The results at echocardiography are compared with those found in some other patients where an echo from the anterior tricuspid leaflet could be obtained (atrial septal defect, total an...

BACKGROUND Echocardiography plays an integral role in the diagnosis of congestive heart failure including measurement of left heart pressure as well as mechanical dyssynchrony. METHODS In this report we describe novel therapeutic uses of echo pulsed wave Doppler in atrioventricular pacemaker optimization in patients who had either not derived significant symptomatic benefit post biventricular...

BACKGROUND/AIM Some endoscopic ultrasonographic (EUS) features have been reported to be suggestive of malignancy in gastrointestinal stromal cell tumours (SCTs). The aim of this study was to assess the predictive value of these features for malignancy. METHODS A total of 56 histologically proven cases of SCT studied by EUS between 1989 and 1996 were reviewed. There were 42 gastric tumours, 12...

The mechanical behavior of tendons has been well studied in vitro. A noninvasive method to acquire mechanical data would be highly beneficial. Elastography has been a promising method of gathering in vivo tissue mechanical behavior, but it has inherent limitations. This study presents acoustoelasticity as an alternative ultrasound-based method of measuring tendon stress and strain by reporting ...

Neutralizing antibody titers of 252 random serum samples from different age groups were determined by the microplate method. The results showed marked differences in the grade and pattern of dissemination among the serotypes. Echo-22 (Group I) showed extremely high endemicity with an infection rate higher than 50% among infants within the first year of life. Cox B-1, 3, and 4 and Echo-9, 11, 14...

Reverberation caused by sound re ected o surfaces and objects is present in abundance in everyday life. Yet, in most situations we are unaware of it. This is due to the ability of our auditory system to adapt to the incoming sound re ections, which results in increased echo thresholds, i.e. the minimum delay to hear a re ection as an echo is increased after the echo was heard repeatedly. Change...

OBJECTIVE Patients with overt hypothyroidism show decreased echogenicity of the thyroid at ultrasonography (US). The aim of this study was to investigate the association between echogenicity of the thyroid/irregular echo pattern, and thyroid function in the general population, i.e. subjects without overt thyroid disease. DESIGN A cross-sectional investigation of 4649 randomly selected adult s...
